The parties contracted on a JCT with Contractor’s Design 1988 Edition. Clause 39A provided that disputes could be referred to adjudication. Application No. 20 on 28 October 2004 was for the gross sum of £748,447.64. No payment was made and a withholding notice was not issued.

The claimant notified the defendant that they intended to refer the dispute to adjudication. The notice was sent by special delivery to the usual place of business and an application was made to the RICS for an adjudicator. The notice of adjudication did not reach the defendant, and so a second notice of adjudication was served on 15 December. On the same day a further application was made to the RICS to re-nominate the same adjudicator.

The defendant argued that there was no dispute at the time of the reference because the service of the notice was not in accordance with the contract. Second, the contract required the notice to be issued before an application was made to the RICS. Third, there was a breach of natural justice in that the adjudicator asked the claimant to provide evidence in respect of which interim payments had been made and how they had been made.
